Combat Robotics

Engineer a robot's drive, weapon, and armour, then battle in the arena.

Design, build, and drive a fighting robot, then send it into the arena against another.

Knife Making

Make knives by stock removal — grinding, heat-treating, and handling steel into a finished blade.

Grind, heat-treat, and handle a blade from a bar of steel — a real knife you made yourself.

Which is right for you?

Choose Combat Robotics if…

  • A complete, hands-on engineering education across motors, power, radio, and structure.
  • The arena adrenaline and a genuinely friendly, helpful community.
  • Cheap entry classes (antweight/beetleweight) keep the first bot affordable.

Choose Knife Making if…

  • A genuinely useful, beautiful object at the end — and you made every part of it.
  • Low barrier to start: files, a vise, and a bar of steel are enough.
  • Deeply tactile, physical making that gets you off screens entirely.

Before you commit

Combat Robotics

  • Your robot will get destroyed, so repair and iteration are the real hobby.
  • Ongoing costs add up: spare parts, batteries, and travel to events.
  • A steep start across several disciplines at once, and a workshop to build in.

Knife Making

  • Hot, dusty, sparky work that needs a garage, shed, or dedicated space.
  • Heat-treating is its own skill (or a send-out cost) and makes or breaks the blade.
  • Hand-grinding is slow; a belt grinder is the upgrade everyone eventually wants.
